Really?
So if i sell you a sports car, and a month later you discover it can't top 100 Km/h, i can say i don't owe you anything because those speeds are illegal anyway?
I'm sorry, dude, but are you listening to yourself?..
Purchasing a product does not make you a stakeholder in the company that made it. Unless you were forced to buy the Kemper, then you made the decision to buy it with the information made available to you at that time. Kemper does not owe any of us rights or insight into intellectual property just because we purchased their product.
